Estimation of missing data in a geophysical series of precipitation

open access: yes, 2021
The analysis of dynamic systems is a topic of great interest in the basic sciences since it allows direct inference of the behavior of different systems. The study of physical phenomena provides large databases that, if recorded at regular time intervals,

The Efficient Techniques for Non-Linear Fractional View Analysis of the KdV Equation

open access: yesFrontiers in Physics, 2022
The solutions to fractional differentials equations are very difficult to investigate. In particular, the solutions of fractional partial differential equations are challenging tasks for mathematicians.

New integral functions generated by rising factorial powers

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2013
We consider new nonelementary functions such as the Fresnel integrals, generated by rising factorial powers. Graphs of such functions are plotted and some of their properties are proved.

PARAMETERS IDENTIFICATION OF THREE-PHASE TO CONTINUOUS CURRENT SYSTEMS DEVICES BY THE TIME SERIES METHOD

open access: yesNauka ta progres transportu, 2018
Purpose. The scientific work provides for the development and justification of a new method for the parametric identification of electric traction devices based on a system of orthogonal functions, namely – on the basis of time power series. Methodology.

Power series, power serious [PDF]

open access: yesJournal of Functional Programming, 1999
Power series and stream processing were made for each other. Stream algorithms for power series are short, sweet, and compositional. Their neatness shines through in Haskell, thanks to pattern-matching, lazy lists, and operator overloading. In a short compass one can build working code from ground zero (scalar operations) up to exact calculation of ...

A New Electromagnetic Emission Source Frequency and Factor Identification Approach for Nonlinear Circuits From the Output Spectrum Data

open access: yesIEEE Access, 2020
For the practical nonlinear circuits, a number of new frequencies are generated in the output spectrum, which makes electromagnetic interference location quite challenging. To mitigate this problem, an approach is proposed to identify the electromagnetic

Natural Frequencies of Axisymmetric Vibrations of Thin Hyperbolic Circular Plates with Clamped Edges

open access: yesInternational Journal of Applied Mechanics and Engineering, 2017
A free vibration analysis of homogeneous and isotropic circular thin plates with nonlinear thickness variation and clamped edges is considered. The limited independent solutions of differential Euler equation were expanded in the power series based on ...

Living and Working Safely Around High-Voltage Power Lines. [PDF]

open access: yes, 1998
High-voltage transmission lines can be just as safe as the electrical wiring in the homes--or just as dangerous. The crucial factor is ourselves: they must learn to behave safely around them.

STATCOM Model Using Holomorphic Embedding

open access: yesIEEE Access, 2019
Convergence characteristics of existing Newton-Raphson (N-R) load-flow based FACTS devices models are affected by the choice of initial conditions. Many a time, a solution is either spurious or fails to converge.
